Siu yeh (Chinese: 宵夜 / 消夜; pinyin: Xiāoyè) is a late night meal in the food culture of Hong Kong. It comes after dinner, and is similar to supper. Mealtime may start from about 9pm onwards until 4am, which would be early morning yum cha time. It can range anywhere from a snack to a full-fledged meal. For people working late night shifts, siu yeh is also associated with their post-midnight meals. Siu yeh is also common in some parts of southern mainland China, and is known there as yexiao (夜宵; pinyin: yèxiāo) in Mandarin Chinese.
